Sync music, photos, and videos that you enjoy viewing or listening from a favorite multimedia app on your computer.
This app should support the Media Transfer Protocol (MTP).

For example, if you have
Windows® 7 on your computer, you can open
Windows Media® Player and sync
HTC Jetstream as a portable media device.

Important: Depending on your computer's operating system and the multimedia app you're using, you may need to obtain and install the MTP driver to work with
HTC Jetstream on your computer. Refer to your computer’s user guide to learn more about media syncing via MTP.
